I would strongly suggest getting out of this habit. There are effects around your avatar when procs happen for a reason. CDs you should get a feel for after playing the specialization for awhile. It's just a recipe for disaster if you get into the habit of bar staring.
While I would love that, for example retaliation makes my eyes glow, which would require me to have my camera facing my character instead of the boss (Jugg tank.) Its a real problem for Juggs. We are very CD and proc heavy. Plus, the enemy castbar is all you need, not the graphics of what an enemy is doing.
